Technaxx TX-81 Activity Tracker black — Smart, simple fitness tracking

The Technaxx TX-81 Activity Tracker black is an affordable, user-friendly fitness wristband designed for everyday activity monitoring. Sleek and lightweight at 25 g, the TX-81 combines a 1.06" color TFT touch display with Bluetooth 4.0 BLE connectivity and an AMS AS7000 heart-rate sensor to deliver core fitness features: step counting, distance, calorie estimation, heart-rate measurement, sleep tracking and notifications from your smartphone. With IP65 splash protection and a flexible TPU strap, it suits outdoor use and daily wear while offering a magnetic Micro USB charging base for convenient recharging.

The tracker pairs with the free My Fitness Plus app (iOS 7.0+/Android 4.3+) to sync activity history, set goals, create reminders and view daily/weekly/monthly charts. Automatic sleep detection, manual sleep mode and preset sleep windows give flexible sleep reporting. The device supports manual heart-rate reads and optional automated tracking intervals, using photoplethysmography (PPG) to detect pulse. Additional conveniences include music control, a camera snapshot remote, smartphone finder, vibrating alerts for calls/messages/social apps, and anti-lost Bluetooth disconnect warnings.

Battery life and charging

Equipped with a built-in 100 mAh LiPo battery, the TX-81 charges in about two hours and typically provides around five days of standby depending on usage and Bluetooth activity. The band must be fully charged before first use and should be recharged every 2–3 months when unused. Note that Bluetooth is disabled while charging and screen illumination remains on during the charging process.

User experience and app integration

The wristband’s interface is gesture-driven: double-tap to wake, slide to navigate, and tap icons to start timers or heart-rate readings. The My Fitness Plus app handles pairing, account management, goal setting, reminders and firmware upgrades. Auto-sync, quick-view wrist raise and notification preferences are configurable in the app; data stored on the band lasts up to five days before syncing is recommended. Factory reset and restart options are available in settings to resolve persistent issues.

Durability and care

IP65 splash protection allows use in light rain or handwashing but prohibits showering, swimming or submersion. Avoid extreme temperatures, abrasive cleaners and physical abuse. The manufacturer provides a two-year warranty and technical support via email or service phone.
